1) soil regime faced when, the present invention has taken into full account that shield machine works, by ultrasonic vibration and shield tunneling
It is combined, the ultrasonic vibration as caused by ultrasonic vibration head, the characteristics of with high frequency, cumulative, will effectively can gathers together
Soil particle is broken up.Simultaneously in aqueous soil, ultrasonic wave can also trigger cavitation strong at liquid-solid interface, cavitation bubble
The high-speed jet produced when bursting apart and shock wave can cause solid particles surface diffusion layer to stir, so that former between destroying soil particle
What is had is cementing so that soil becomes softer, is more easy to by digging excavation.
In sum, by ultrasonication-Shield digging, the two processes organically combine the present invention, can not only have
Effect improves Advance rate, can also reduce shield machine tool bit abrasion, extends its service life, so as to reduce engineering cost.
2), in the present invention, for Vltrasonic device, its ultrasonic transducer, ultrasonic transformer, emitting head have to pass through tightly
Design with adjustment, can be only achieved good couple state and normally run, it is contemplated that the complexity of shield machine cutter head structure, directly
Connect and be difficult to reach above-mentioned couple state by itself and the way that transducer, ultrasonic transformer are connected, so may result in its operating efficiency
Substantially reduce, or even cisco unity malfunction.Therefore select for ultrasonic vibration rod to be arranged on shield enclosure interior in the present invention, and
Emitting head uses at present standard pattern (polished rod, rhombus etc.) on the market, so not only it is possible to prevente effectively from complicated knot
Structure cutter head and ultrasonic transducer, ultrasonic transformer mismatch the brought low problem of operating efficiency, also making this method simpler
It is easy.
3), the cutting knife on ultrasound wave vibrating bar of the present invention and cutterhead is individually present, it is possible to prevente effectively from due to transmitting head height
The adverse effect that frequency vibration is produced to cutter head；Also, auxiliary ultrasonic vibrating head is also equipped with the circle centre position of cutterhead, auxiliary is super
The cross sectional dimensions of the ultrasonic wave emitting head of acoustic vibration rod is to be clipped in the ultrasound wave vibrating bar in the middle of two symmetrical cutting knifes
2~3 times of ultrasonic wave emitting head cross sectional dimensions, the two works in coordination to ensure excavation effect.
